To be honest I think it's more about how you shave. All electric razors in this price range are pretty much on par in quality.For me I found out it's best to shave every day (even though I don't really need to) for 2-3 minutes instead of every third day for let's say 6 minutes.I also use a few drops of jojoba oil to minimize the friction.

The trimmer is very useful too. Obviously it doesn't make your face as smooth as the razor itself but it's better than nothing. Also when my acne is super inflamed I rely mainly on the trimmer to avoid any more irritation because scraping off the pustules probably isn't a very good idea.
